tical or slightly clavate, 8-10 x 2 /x ; paraphyses slender,

Type specimen examined. 



Dasyscypha abietis, Sacc, Syll., viii. n. 1824. 



Scattered or gregarious, narrowed into a short, stout, stem- 

 like base, rather fleshy, 1-1 '5 mm. across; disc orange- 

 yellow, externally white and villose, hairs rather wavy, 

 cylindrical, obtuse, thin- walled, septate, colourless, 150— 

 200 X 4-5 /a ; cortex formed of oblong cells in parallel rows 

 running from base to margin, 6-7 X 3-4 jx ; asci broadly 

 clavate, gradually tapering downwards from the broad, very 

 obtuse apex, 8-spored ; spores 2-seriate, hyaline, elliptic, 

 ends very acute, straight or slightly curved, 2-guttulate 

 then 1-septate, 12-14 x 3 fx ; paraphyses hyaline, cylindrical, 

 tips rather pointed, 2*5-3 jx thick, longer than the asci. 



Lachnella abietis, Karsten, Rev. Mon., p. 131. 



On Abies excelsa. 



The above description is drawn up from the specimens in 

 the Kew copy of Karsten's Fung. Fenn., no. 837, with which 

 British specimens exactly agree. 



So far as the external characters of the ascophore are con- 

 cerned, the present species is practically indistinguishable 

 from D. calycina and D. subtilissima. The three sjjecies may 

 be contrasted as follows. 



D. calycina, spores 18-25 X 6-8 /x. 



J), subtilissima, spores 8-10 x 2 //., paraphyses same length 

 as the asci. 



D. abietis, spores 12—14 X 3 /x, paraphyses longer than the 

 asci. 



Dasyscypha resinaria, Rehm, Ascom. Lojk, n. 30; 

 Sacc, Syll., viii. n. 1826. 



Gregarious; ascophore stipitate, turbinate then expanded, 

 margin more or less persistently incurved, |-1 mm. across, 

 1 J mm. high, externally white, the short stem and excipulum 

 clothed with short, spreading, unbranched, septate, white 

 hairs about 40-60 x 4 /x, rough with minute, external parti-
